THE DUST OBSERVATORY

📜 Briefing
Far out in the desert, past the last road sign, stands a white dome that stopped answering calls years ago. Its keeper vanished one night, and the only thing left running is a faint pulse sent from the old receiver on the hill.

You have slipped past the fence with a borrowed key and a flashlight that is already dimming. Each room holds a message the keeper hid for whoever came looking. Find them all in order, and the pulse may finally tell you where the keeper went.
